Temperature Transmitters Model KM
Description
Transmitters for head mounting model KM, transform
resistance values or thermal voltage into a standard current
signal 4 ... 20 mA. Transmission is absolute interference-free
over long distances.Different sensor inputs are Resistance
thermometers, Thermocouples, Resistance and Voltage.
Programming of measuring ranges is via U-pro and HART®
protocol. Connection head for mounting these U-pro transmitters is according to DIN 43 729 form B.
